Over my head
Sorry, I took a look at both of those links and I feel I am in over my head. I don't understand Modulus of Elasticity, etc.
Plus they are talking about joist spacing, but I'm having a hard time understanding how to correlate that to a single beam span across to end anchor...
I'm going to build a swingset/gym in my 4yr old's bedroom so during the winter he can satisfy his climbing needs without climbing on me :smile:
How can I calculate the height (or thickness) of the beam I will need to use to support his weight, and perhaps the weight of a couple of his...
